Advanced Searching Tips

When you first visit the Advanced Search page, you are presented with
several search fields. In each field, you can type the keywords you
want to search for. Search operators
are allowed.

Each field is accompanied by a drop-down that lets you specify the type
of data (title, author, etc.) you are searching for. You can mix and
match search types however you like.

The "Match" setting lets you specify how multiple search fields should
be handled.

ALL Terms - Return only records that match every search field.

ANY Terms - Return any records that match at least one search field.

NO Terms -- Return all records EXCEPT those that match search fields.

The "Add Search Field" button may be used to add additional search fields
to the form. You may use as many search fields as you wish.

Search Groups

For certain complex searches, a single set of search fields may not be
enough. For example, suppose you want to find books about the history of
China or India. If you did an ALL Terms search for China, India, and
History, you would only get books about China AND India. If you did an
ANY Terms search, you would get books about history that had nothing to
do with China or India.

Search Groups provide a way to build searches from multiple groups of
search fields. Every time you click the "Add Search Group" button, a new
group of fields is added. Once you have multiple search groups, you can
remove unwanted groups with the "Remove Search Group" button, and you can
specify whether you want to match on ANY or ALL search groups.

In the history of China or India example described above, you could solve
the problem using search groups like this:

In the first search group, enter "India" and "China" and make sure that
the "Match" setting is "ANY Terms."

Add a second search group and enter "history."

Make sure the match setting next to the Search Groups header is set to
"ALL Groups."
